AT88SC0104C
2021BS–SMEM–10/02
grammed into the 64-bit answer-to-reset register. An internal pull-up on the RST input
pad allows the device to be used in synchronous mode without bonding RST. The
AT88SC0104C does not support the synchronous answer-to-reset sequence.
Device Architecture
User Zones
The EEPROM user memory is divided into 4 zones of 256 bits each. Multiple zones
allow for different types of data or files to be stored in different zones. Access to the user
zones is allowed only after security requirements have been met. These security
requirements are defined by the user during the personalization of the device in the con-
figuration zone. If the same security requirements are selected for multiple zones, then
these zones may effectively be accessed as one larger zone.
Table 2.
User Zones
Control Logic
Access to the user zones occurs only through the control logic built into the device. This
logic is configurable through access registers, key registers and keys programmed into
the configuration zone during device personalization. Also implemented in the control
logic is a cryptographic engine for performing the various higher-level security functions
of the device.
